character which is air-tight and yet accommocflatesexpansion and contraction due to changes in the weather. A further object is to provide means for reliably securing a stave silo to a firm and rigid anchorage, without interfering with automatic lateral edgewise movement of the staves with respect to each other. A still further object is to provide a stave silo inwhich staves at opposite sides of the door frame are rigidly secured to: the latter and abut firmly at their outer edges againstthe inner edges of the adjacent staves so as to form an air-tight joint between the adjustable staves and the said frame. Another object is to produce a silo embodying all of the desirable features of the silo exemplified in United States Patent 1,145,306, issued on July 6th, 1915, to the J. L. Jones Manufacturing Company, of Kansas City, Missouri, but of simpler and more durable construction than the" silo r of said patent.

With the objects pointed out in view, the invention consists in certain novel and use ful features of construction and combinations .of parts as hereinafter described and claimed; and in order that it may be fully understood reference is to be had to the all accompanying drawing, in which Figure l, is afront elevation of a silo embodying the invention.

Fig. 2, is an enlarged horizontal section taken on the line llI-ll of Fig. 1. j

in the said drawing 1 is an anchorage frame of the type disclosed in the aforesaid patent, and '2 designates angle-brackets secured upon said frame midway the len 11 of its sides and back, each bracket of which two only are shown, having an upwardlyprojecting perforated arm 3,. for a purpose which hereinafter appears.

Extending vertically through the said frame is the silo constructed as follows:

the staves except two are provided with saddle clips 9 through which extend stave anchor tubes 10, the ends of said tubes extending convergingly forward through the timbers or posts 4: of thedoor frame, the two staves referred to as having no saddle clips, being secured to the said posts and abutting at their outer edges against the inner edges of the adjacent staves. it will be noted that there area number of the stave anchor tubes, one in the horizontal plane oi. the perforations of arms 3, and xtending through said arms to secure anchorage to the anchorage frame, and it will be under stood that the particular staves adjacent said arms are not provided with the saddle clips so that conflict with said arms shall be avoided.

Encircling the staves are a number of cable clamps 11, attached at their ends to eye-bolts IQeXtending through the posts 4 and engaged at the inner sides of the latter by retaining nuts 13, whereby to exert clamping pressure on the silo to bind the staves thereof firmly together and against the two staves secured to posts 1, with an air-tight joint, it being understood that as the silo is thus clamped, the sliding of the staveanchor tubes in the posts 4, tends to press the staves fastened to posts a and the adjacent staves firmly together and thus maintain an air-tight joint between the laterally adjustable staves and the door frame. The cable clamps are retained in proper relation with the staves by passing through clips carried by occasional staves, as at 14:.

A silo of the construction described, can be manufactured at low cost, will resist heavy wind pressure, and in dry weather the saddle clips will retain the staves in proper position, that is will guard against the staves falling inward. It will be apparent that the silo is susceptible of minor changes without a stave secured to the inner face of each side of said frame, a series of staves fitted edgewise together, in'cylindrical form, anchor at their ends through the sides of the door frame, at angles diverging outward with respect to the outer faces of the staves secured to said sides, and means for clamping the series of staves equipped with the saddle clips, against the outer edges of the two staves secured to the sides of the door frame.

'2. A silo comprising a rigid door frame, astave secured to the inner face of each side of said frame, a series of staves fitted edgewise together in cylindrical form, anchorage devices externally of and conforming to the cylindrical arrangement of said series of staves, saddle clips secured to staves of said series and fitting slidingly on said anchorage devices; the said devices extending at their ends through the sides of the door frame, at angles diverging outward with respect to the outer faces of the staves V secured to said sides, and cable clamps externally embracing the staves and secured to some of them and adjustably to the opposite sides of the door frame.

3. A silo comprising an anchorage frame provided at a plurality of points with angle brackets having upwardly-projecting )erforated arms, and a silo proper exten ing vertically through said frame, comprising a door frame, boards bridging the space between the sides of said frame, a pair of staves secured to opposite sides of said frame at the inner side thereof and projecting beyond the outer sides of said frame, a series of staves fitted edgewise together and against the outer edges of the said pair of staves, saddle clips secured to each of the said series of staves, arcuate devices externally engaging the series of staves and extending slidingly through the sides of the door frame in a forwardly and outwardly direction, one of said arcuate devices extending slidingly through the said perforated arms to anchor the silo proper to the said anchorage frame, a series of cable clamps extending around the staves, clips secured to some of the staves and fitting over said cable clamps, and means for adjustably securing the ends of the cable clamps to the door frame to clamp the staves firmly tog'ether.

In testimony whereof we aflix our signatures.
